RE: octane meathods

[Aleksander Mierzwa <alex@matrix.com.pl>]

Actually in the manual for my 87 5KCST they recommend at least 92AKI
gas, which corresponds to about 96-97RON. (Gas pumps in Europe are
labeled using RON, in US using AKI, which is (RON+MON)/2). I've been
informed that the MC motor will run fine on 87AKI, though.
